Is there any way to force the commit to happen, even if the script
doesn't like it?  Can the script edit the commit message, even?  ie if
there's no git commit --ignore-prehook type option, could it see if the
first line is FORCE or something, edit that out and commit?  This will
catch the poorly formed commit messages without being a big burden on
people doing things that don't fit well into the "module: summary" model
(that said, lib*-perl-native: Convert to BBCLASSEXTEND as a first line
makes sense to me).
